At the north, adjacent to the Castle and Canteen building, Portland stone and red brick are predominantly employed to sit comfortably with their surroundings. Feature gables are accented with diaper pattern brickwork whilst on the rest of the site a more restrained, understated palette of sandy brick colours is employed. Large, uninterrupted picture windows are complemented by smaller, separate opening vents to provide all houses with extensive views out to the unique context and will ensure that all houses feel generous and light filled inside. The windows are framed by cast stone surrounds that emphasise the importance of the views and offer relief and articulation in the otherwise simple gabled forms. These details are complimented by a range of brickwork including soldier courses and expressive brickwork eaves coursing all of which is designed to softens and humanise the architecture.
